Objectives:
This article discusses the administrative and legal activities of the minister responsible for tourism in the field of experimental methods of studying tourist traffic. These methods include the use of many data sources, the so-called “big data”. The discussion will cover cooperation with South Korea and domestic entities - including Statistics Poland and the National Bank of Poland.

Material and methods:
The research methods used in the article are the comparative method, which requires a comparison of Polish and South Korean regulations. Additionally, the dogmatic-exegetical method was used, which requires familiarization with the existing literature. The article aims to show good patterns in experimental methods of studying tourist traffic and encourage readers to learn about modern technologies in this area planned for use in Poland.

Results:
This article was written as part of the activities of the steering committee of the project "Advanced AI tools and algorithms based on public data supporting economic development in the field of tourism," co-financed by the National Centre for Research and Development under the Strategic Research and Development Program "Advanced information, telecommunications and mechatronic technologies" – INFOSTRATEG VIII.

Conclusions:
All the effects described above will be of assistance not only for entrepreneurs but also for central government and local government tourism administrations. The knowledge on real tourist traffic will e.g. make it possible to counteract the phenomenon of the grey zone in tourism that results from conducting non-registered business activity. The broad use of the experimental methods for tourist traffic tracking, discussed in this paper, shows how important this reception area is.
